The group where the member who comes from Seoul speaks in dialects

is BTS

RM

Most of his teammates are from Busan, Daegu, and Gwangju. Since they all speak in dialects, it automatically becomes his habit tooㅋㅋㅋㅋ He really does speak in dialects a lot, you'll notice it if you watch videos of him on Youtube

1. [+102][-0] I think the dialect he uses is a mixture of various dialects that his teammates use, since he has lived together with him for a long timeㅋㅋㅋㅋ Namjoon's own dialect is called Namturi...

2. [+81][-0] An example of Namturi: Can't --> Caaan't 

3. [+63][-0] They're just like a real family... I'm not a fan, but the sight of them warms my heart

4. [+33][-0] It's because Jung Hoseok uses dialects a lot around himㅋㅋㅋ Even the members from Gyeongsang-do sometimes speak in Jeolla-do dialect

5. [+21][-0] This reminds me of that one time Jimin telling a joke to everyone that his nickname was 'Lovely', then Jung Hoseok in the back suddenly went Lo\\vely//???ㅋㅋㅋㅋㅋ His facial expression was so serious, I couldn't stop laughing at that time

6. [+18][-0] Including Kim Seokjin, it's so chaoticㅋㅋㅋ He speaks in Gyeongsang-do dialect with Gwangju languageㅋㅋㅋㅋ
